RSS guidelines

The arguments continue to rage about the ambiguities in the RSS specifications. But the fact is: RSS is here to stay, and defined specification likely is going the current RSS 2.0 as well, as it is going to be have. Attempts were made to "best practice" to create documents and specification clarifications. We found that it would be helpful, General guidelines for the construction of an RSS 2.0 feed. In General, the following guidelines to build up a are RSS-feed. It is good to the habit of checking the RSS feed, either software or an online validator. Here are some general guidelines for creating RSS feeds: 1. Cases are only a case per article for maximum compatibility. The RSS 2.0 specification does not clearly indicate whether multiple enclosures are allowed or not, but only a single enclosure supports most RSS readers. It is therefore, correspond to the reader, and an enclosure only take in each RSS feed item. 2. Date formats date formats can be very difficult; Make sure that all data is correctly formatted. 3. Encodingencoding is required for certain characters. If you are using software to create the feed, it should treat the character encoding for you. 4. HTML while the specification is not explicit, it is a good idea in General, do not use HTML coding within the channel or the object title. For maximum compatibility, feed is the only place that you should use HTML in the RSS feed item description. 5. GUID GUID (global unique identifier) are not required. Publishers but recommended, use a unique string in the GUID field. Many RSS readers are looking for GUID changes to determine whether new items in a RSS feed are available. 6. Images , if you mount an image with the feed, the recommended image size is 88 x 31 (the maximum allowed size is 144 x 400). If you also are RSS-feed item description or housing areas of a picture in the, no size limits exist, but keep in mind that excessively large graphics will have a negative impact on the amount of time, that it takes to load the feed. 7. Favicons some RSS readers and search engines display the favicon hosting area next to the entry for an RSS feed. To withdraw your feed to be sure you domain include a favicon in the root directory of your site. 8. URLsfor images, Web sites and links, instead "relatively" use "absolute" URLs URLs. The intent of RSS is to syndicate content, so that the RSS feed may not always local to the person to view the feed. So the full Web path should be to all images, Web sites and links are used. In other words, you do not use ".."/ ImageUrl.gif ", but the full URL"http://www.mydomain.com/imageurl.gif"beim use linking of content." 9. Title, use a descriptive title for the channel feed and RSS feed items. Most RSS directories and search engines use the words in the channel title and item title classify RSS-feeds.10. MIME types, if you include a file in the case of an RSS feed, sure, "Size", and "Mime type" of the case look to define file properly. Here - http://www.feedforall.com/mime-types.htm for a list of the correct MIME type formats. 11. Auto-discovery , RSS-feed "autosense mode" include code in your HTML page header. It will make sure that browser and RSS feed reader automatically know that an RSS feed for specific content is available. To create the AutoDiscovery code - http://www.feedforall.com/autodiscovery.htmvolume 12 the number of items in a feed is important. Set a story and expand the feed on a regular basis. Crop the RSS feed if it is excessively long; This will help to make the RSS feed load faster. About the author:
